Is there any documentation on the card that could help us?



Hi Paulo,
try link (its about chip DS21[35]54 on e100p):
http://www.maxim-ic.com/appnotes.cfm?appnote_number=481

afaik wct1xxp don't send E-bit (bit 2 of "Transmit Control Register 2" must be set to 1 to set E-bit) so Telco side have no info about CRC

if you wisch i can send you my version of wct1xxp, unfortunately old CVS - 15-09-2003 and dirty code :-( , working good with Lucent 5ESS on Telco side. (contact me off-list)
additionaly this patch show some info about errors on E1 line: VCR,CRC,EBCR and FASCR
and is possible to change input impedance from 120 OHM to 120 OHM with resistors or 120 OHM with high resistors - just for test purposes.



Konrad
